SPECIFICATION forming part of Letters Patent No. 309,986, dated December 30, 1884.

Application filed October 23,1684. (X0 model.)

To all whom it may concern Be it known that LJOHN W. SMITH,L citizen of the United States of America, residing at Kilmore, in the county of Clinton and State of Indiana,have invented certain new and useful Improvements in Tile-Kilns, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, forming a part of this specification.

My invention relates to certain new and useful improvements intile-kilus; and it consists in the construction and combination of the parts, as will be hereinai'terfully setforth, and pointed out in the claims.

In the accompanying drawings, which illustrate my invention, Figure l is a vertical section; Fig. 2, a horizontal section taken above the fioor of the kiln. Fig. 3 is a horizontal section taken through the lire-boxes and draftarches.

A represents the cylindrical wall of the kiln, which is provided with the usual door for having access to the interior of the same.

B represents the arched top, which is provided with chimneys b, and centrally with a heat-deflector, G, which consists of a conical depending plate, which is secured to the interior of the central portion of the top immediately above the central flue, D, which is supported within the kiln.

E represents radiating fireboxes, each of which opens into the central flue.

F represents draft-arches,which are located between the fire-arches E, and these draftarches are provided with upwardly-projecting ventilating-tubes f, which project upwardly near the exterior of the kiln. Between the fire and draft arches, so as to extend on a line with the top of the fire and draft arches, are segmental walls G G, so as to form openings or passage-ways which com municate with the openings f in the draftarches F. Above the segmental walls G G and the top of the fire and draft arches is built the bottom of the kiln, upon which the tiles to be baked are placed. This floor is built or laid substantially as shown in Fig. 2, so as to be selfsupporting and provide at the same time openings through which the heat can pass, as well as communicating with the draft-arches. The draftarches are preferably constructed of boiler-iron, and are provided with doors 9, for having access to the interior of the same. The fire-arches are built up of brick and masonry, and when the fires are started therein,thetiles having been first placed within the kiln, caps are placed over the upwardly-projecting tubes f of the draft-flues, and the heat will ascend the central flue, D, and pass out of the chimneys to the upper part of the kiln, this escape of heat being allowed until the arches are thoroughly dry, thus obviating the deleterious results of the moisture upon the tiles. After the firearches are thoroughly dried, the caps are removed from the vertical tubes f of the draftarches, which draft-arches are provided with dampers, and the heat from said fire-boxes and draft-arches allowed to ascend so as to bake the tiles. Both of the fire-arches and I draft-arches are provided with dampers for controlling the heat. The deflectors 0 will disperse the heat in the top of the kiln and prevent the crown from burning out.

lVhen desirable, the upper port or chimneys, I), may be closed and the heat will ascend in the fiue D, be diverged by the deflector G, and will be drawn downwardly over the tiles through the openings in the floor and upper part of the draft-arches and escape through the tubes f. This is the most economical manner of operating the kiln, and usually the ports I) should be closed immediately after the fire-arches become thoroughly dried.
